“My dream has come true. I have always wanted to be a Grand Slam (大满贯) champion.” These are the words of Chinese tennis player Li Na after she became the first Asian woman to win a Grand Slam final in the French Open on June 4, 2011.

“People were saying I’m getting old. So this is a great success for such an old woman,” the 29-year-old girl joked.

Miss Li has a tattoo (纹身). She has dyed her hair many different colors. And, at the 2008 Beijing Olympics, she told her fans to “shut up” when they got too noisy in their support.

Li Na was born in Wuhan, she started to play tennis at the age of 6. She once reca lled: “As a child, I felt sad because every day I had to wake up early to practice. After school I had to practice more. I didn’t have time to play.”

Luckily, the strong girl didn’t give up, thus making history for Chinese tennis time after time. Now the new champion is already thinking about winning another Grand Slam title. “When you have one title, surely you will think about another,” she says, not hiding her ambition (雄心).“Chinese people are so lacking (缺乏) in confidence on the tennis court. If there is a person like me who can prove we Chinese can do it, the other young players in China will feel the same,” she said.

45. When she began to play tennis, Li Na was _____.

A. happy

B. sad

C. excited

D. bored

46.The underlined word “dyed” here means “_____” in Chinese.

A. 焗油

B. 洗烫

C. 染色

D. 梳理

47.Which of the following is WRONG about Li Na?

"It’s over! Thank goodness!"

School was over and I was tired. I sat at the front of the school bus.

Janie, the driver, always tries to break the uncomfortable atmosphere by talking. I try to listen poli tely, but usually I’m too busy thinking about my day. On this day, however, her talk was worth listening to.

"My father’s ill," she said to no one in particular. I could see worry in her eyes. I had never seen her like this before. She always meets students with a smile.

With a sudden chance of interest, I asked, "What’s wrong with him?"

With her eyes wet and her voice unusual, she answered, "Heart trouble." Her eyes lowered as

she continued, "I’ve already lost my mum, so I don’t think I can sta nd (忍受) losing him." I couldn’t answer. My heart ached for her.

I sat on the seat thinking of the great pain my own mother was thrown into when her father died.

I saw how hard it was, and still is, for her. I wouldn’t want anyone to go through that.

Suddenly I realized Janie wasn’t only a bus driver, which was just her job. She had a whole world of family and cares too.

I shouldn’t have been so selfish. I paid no attention to Janie because she was a bus driver. I had judged (判断)her by her job and brushed her off as unimportant.

I shouldn’t have been so selfish and self-centered. Understanding people is an art.

48. When the students get on the school bus, Janie usually__________.

A. listens to music

B. talks about her own worry

C. sits on her seat without words

D. meets them with a smile

49. The writer felt herself selfish because she had__________.

B. made only a few friends in the school

C. hardly thought of herself

D. never listened to others

50. In this passage the writer tries to tell us that__________.

A. losing parents makes people sad and helpless

B. understanding the people around us takes time

C. we should learn to understand the people around us

D. it’s not right to judge the people around us by their clothes

If you want to become a better reader,what should you know about speed of reading? Some people read very rapidly(很快地),while others read very slowly. But which one is better?

The rapid reader may be a good reader when he reads a storybook for fun. But he may not be able to slow down enough to read directions(说明) carefully. He may read so rapidly that he does not take time to understand fully the ideas and information which are important to remember.

The slow reader may be a good reader when he reads directions for making something. But he may spend too much time in reading a simple story which is meant to be enjoyed but is not important enough to be remembered. So,you see,either a rapid reader or a slow reader is not really a good one. If you wish to become a better reader,here are four important things to remember about speed of reading.

1. Knowing why you are reading will often help you to know whether to read rapidly or slowly.

2. Some things should be read slowly throughout. Examples are directions for making or doing something,science and history books,and Maths problems. You must read such things slowly or remember each important step and understand each important idea.

3. Some things should be read rapidly throughout. Examples are simple stories for enjoyment,letters from friends and bits of news from hometown papers.

4. In some of your reading,you must change your speed from fast to slow and slow to fast,as you go along. You will need to read certain(某些) pages rapidly and then slow down and do more careful reading when you come to important ideas.

51. What should be read rapidly?

A. Directions for making something.

B. Maths problems.

C. Science and history books.

D. Storybooks,newspapers,personal letters,etc.

52. What is the important thing you should know about speed of reading?

A. To read as fast as you can.

B. To fit your reading speed to your needs.

C. To read as slowly as possible.

D. To keep your reading at a certain speed.

53..Which title best gives the main idea of the passage?

A. Something about Careful Reading

B. Be a Rapid Reader.

C. How to Read?

D. How to Be a Slow Reader?

D

How often one hears children wishing they were grown-ups, and old people wishing they were young again. Each age has its pleasures and its pains(痛苦), and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets(后悔).

Childhood is a time when there are few responsibilities(责任) to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What’s more, life is always giving new things to the child--- things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is repeatedly being told not to do something or being punished for what he has wrongly done.

When a young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to as a child, he will go hungry. And if he breaks the laws of society(社会) as he used to break the laws of his parents, he may go to prison. If, however, he worked hard, keeps out of trouble and has good health, he can have the greatest happiness of building up for himself his own position(地位) in society.

54. What is the happiest person according to the passage?

A. A child who can do whatever he likes.

B. An old person who lives in a comfortable life.

C. A grown-up who no longer expects others to pay for him.

D. A person who never wastes his time in his whole life.

55. Which of the following is true, according to the second paragraph?

A. Life for a child is fairly easy.

B. A child is always loved whatever he does.

C. If much is given to a child, he must do something in return.

D. Only children are interested in life.

56. What is the main idea of the passage?

A. Life is not enjoyable since each age had some pains.

B. Young men can have the greatest happiness if they work hard.

C. Childhood is the most enjoyable time in one’s life.

D. One is the happiest if he can make good use of each age in his life.

57. What will the fourth paragraph most probably discuss following this passage?

A. Examples of successful young men.

B. How to build up one’s position in society.

C. Joys and pains of old people.

D. What to do when one has problems in life.

I am writing the letter to complain about the mobile phone I bought from your shop two months ago. Ten days after I bought it, it couldn’t ring or send short messages. I took it to your shop,but the yong man there told me that the model was sold out,and I would have to wait three months for a new one. Later, I went to the repairman. He said it was a new model, and it was impossible to repair the phone without the right spare parts. I was unhappy when I heard that. How can I wait so long? I would like you to send me a new one within a month,or I want my money back.

Hope to hear from you soon.

Yours sincerely,

Simon

英语试卷质量反馈表2015.4.27

附件1-2: 灵宝市初中试卷质量反馈表学校五亩一中 学科英语年级九 试题分析 本次考试紧扣课标,充分体现了英语课程标准的理念。本次测试共120分,100分钟,其中听力部分占20分,单选占15分,完形填空占10分,阅读理解40分,词语运用10分,补全对话10分,书面表达15分。和中招考试的题型及分值一致。 试卷注重基础,体现灵活运用,难度和区分度恰当无偏题、怪题出现。试题注重考查学生在一定语境下对语言基础知识的掌握情况和综合运用英语的能力。语言基础知识的考查重点突出、覆盖面广;情景设置合理,避免了纯知识性的死记硬背题;词汇和语法的测试充分注意了语言的真实性、趣味性和实践性;注重语感,灵活性强,突出语言形式向语言意义的转化。 试卷(命 题、校对) 存在问题 听力的语速有点快并且读的不太清楚。

学生答题情况分析 从考试的情况看,全年级最高分109分,人均分为75.1分,及格率57.7%,优秀率14.4%。高分率、优秀率和及格率整体偏低。下面就学生答题的情况做简单的分析。 (一)听力 主要涉及的话题有:就医、天气、生日、日常生活等。题目设计以who、what、where、how、why等问题为主。错误率最高的是第一小节的3、5第二小节的6、7、10、11小题及第三节。听力是本次考试中学生答得最差的一道题。因为很多学生没有听清楚人名。 (二)单项选择 本题从21到35小题,共15小题,着重考察学生语言知识的运用能力,侧重于词汇、语法、句法在语境中的运用。错误率最高的是21、23、24、34。尤其是第23题,很多学生不知道green hand 的意思。 (三)完形填空 完型的考察多以实词为主。在这次考试中,失分较多的是41小题。错误率为50%。这道题考查的是动词carry的用法,这个单词的意思大部分学生都懂,但选错的学生很多。主要还是句意不理解。(四)阅读理解 阅读题共20小题,40分。试题难易程度适中,题材新颖。题目设置有细节考察,猜词,推断,文章大意等阅读题型。 本次考试中,这道题错误率最高的小题是51、53、54、61、64,即出错最多的是(B)(D)篇。(B)篇这次是一篇关于3D电影的说明文,有一定的难度。而3D对于农村学生来说,还有些陌生,因此错的较
